..As for exon 7, it was absent in both toad genes. Moreover, the AMBN genes were transcribed only in the upper jaw, presumably in teeth. These results may provide useful information for investigation of the evolution of enamel...

Identification and characterization of integrin-binding sialoprotein (IBSP) genes in reptile and amphibian

..This indicates that continuity of biochemical properties has been more important in maintaining DMP1 functionality than that of the sequence of amino acid residues, which has undergone change over the course of molecular evolution...

..This intracellular behavior of GAS is unique and distinct from that of other types of bacterial invaders. Our results provide a new picture of GAS infection and host-cell responses in epithelial cells...
